Answer:
slope = -1
Step-by-step explanation:
y2-y1 divided by x2-x1
3-7= -4
2-(-2) = 4
-4 divided by 4 = -1
Find a common denominator that 8 and 3 can go into.. which is 24
5/8 = 1/3
15/24 - 8/24
7/24
Hope this helped
Answer:
a) 3 inch pulley: 11,309.7 radians/min
6) 6 inch pulley: 5654.7 radians/min
b) 900 RPM (revolutions per minute)
Step-by-step explanation:
Hi!
When a pulley wirh radius R rotantes an angle θ, the arc length travelled by a point on its rim is Rθ. Then the tangential speed V is related to angular speed ω as:

When you connect two pulleys with a belt, if the belt doesn't slip, each point of the belt has the same speed as each point in the rim of both pulleys: Then, both pulleys have the same tangential speed:


We need to convert RPM to radias per minute. One revolution is 2π radians, then:


The saw rotates with the same angular speed as the 6 inch pulley: 900RPM
Answer:
D
Step-by-step explanation:
Here, we want to compare the graph of g(x) and f(x)
Looking at the given equations, the difference between the two is that we have 5 subtracted from one of the equations
What this means is that we are moving down 5 units away from the graph of f(x) to get the graph of g(x)
Thus, option D is the correct answer
Answer:
18900 watt-hours
Step-by-step explanation:
3600 x 24 (hours in a day) = 150
150 x 6 (hours) = 900
3600 (watt hours per day) x 5 (days) = 18000
18000 x 900 = 18900
total= 18900
